ADJUSTABLE STAND.

Application filed. November To (ZZZ whom it may concern Be it known thatI, THOMAS H. BHEDMON, a citizen of the United States residing atllleadville, in the county of Crawford and State of Pennsylvania, haveinvented new and useful Improvements in Adjustable Stands, of which thefollowing is a specification.

This invention is designed for use in repairing motors, particularlyautomobile mo-- tors. It is desirable to have the motor supported insuch a manner that it may be swung in different positions to provide forconvenience of operation and conditions of light. It is also desirableto have the support so formed that it may be adjusted to differentmotors.

The invention is illustrated in the accompanying drawings as followsFigure 1 shows a plan view of the stand.

Fig. 2 an end elevation. Fig. 3 a side elevation of the base.

Fig- 4: a part of the swinging support.

Fig. 5 a side elevation of the upper end of the frame.

1 marks the base. This is formed of longitudinally arranged angle irons.A wheel 2 is journaled on each rounded end of a squared rod 2 at one endof the base and supporting lugs 3 project from the opposite end of theangle iron base 1. By this construction it is possible to move the standin different positions relieving the weight somewhat from the lugs andyet the lugs supply suiilcient resistance to retain the frame in' theposition where it is desired to operate.

The frame has the upright standards 4c which are formed preferably ofangle irons with a U-bend, one leg being preferaliily vertical and theother slightly at an angle so as to more thoroughly brace the upright. Across beam 5 ext-ends from one leg across the frame and a cross beam 6from the other leg across the frame the lower angle iron of the crossbeams 5 and 6 affording a securing means to the base 1. The cross beams5 and 6 are secured to the legs of the upright or standard by means ofbolts 7 and with the base by means of bolts 7. A brace 8 is secured tothe beam 5 by means of bolts 8 and has the upwardly extending ends whichare secured to the leg of the brace 8 by means of bolts 8. A similarbrace 9 is secured to the cross beam 6 by means of bolts 9 and with theupright by means of bolts 9*. It will be seen, therefore, that the frameSpecification of Letters Patent.

formed with the base and upright standards is very rigid and yet thespace between the standards is open or unobstructed so as to permit ofthe movement of the swinging support within the space.

The upper face 10 of the standard 4: forms a support for a bearing forthe swinging support. This bearing is in the form of a clamp having abase 11, a bend 12 and a projection 13. A bolt 1 1- extends through thepart of the standard 10, the plate 11, projection 13 into an elongatednut 15. A handle 16 extends through the nut 15 by means of which thebearing may be contracted or expanded as desired. The plate 11 ispreferably permanently secured to the upper part 10 of the standard bymeans of bolts 11.

Trunnio-ns 17 are arranged in the clamping bearings and extend from thesides 18 of a swinging support. These sides are in the form of angleirons and are connected with the cross beam 19 by means of the cornerirons 20. The corner irons are connected with the sine beams 18 andcross beam 19 by means of bolts 21. A series of holes 22 are arranged inthe side beams by means of. which the endwise position of the cross beam19 may be adjusted by changing the bolts 21 and the cross beam 19 has aseries of openings 23 by means of which the distance between the sidebeams may be adjusted and the cross beam secured by means of the bolts21. The height of the cross beam relatively to the side beams may alsobe adjusted by utilizing the openings 20 in the corner irons. In thisinstance again the bolt 21 is removed and the cross beam adjusted to thepoint desired.

It will be noted that the trunnions when the clamps are loosened notonly permit of the swinging of the support but permit of the adjustmentof the side beams in and out to any width desired. This gives a verymuch more rigid support than where the entire frame is adjusted inwidth.

\Vhat I claim as new is:

1. In an adjustable stand the combination of a frame comprising sidestandards; a swinging work support; trunnions extending from thesupport; and clamp bearings for the trunnions permitting rotary andaxial movement of the trunnions when released whereby the support may betilted and adjusted in width.

2. In an adjustable stand, the combination of a frame comprisingstandards; a

7 tion of a frame comprising side standards;

a swinging work support comprising side beams and a cross beam; cornerplate connecting said beams, said connections being adjustable;trunnions extending from the .side beams; and clamp bearings for thetrunnions' permitting rotary and axial movement or the trunnions whenreleased whereby the support may be tilted and adjusted in Width.

4:. In an adjustable stand, the combination of a base; standardsextending uprightly from the base; cross beams connectingthe standardsadjacent to the base; braces between the cross beams and the standards;a swinging support; clamp bearings on the standards; trunnions on theswinging support extending into the clamp bearings; and means foradjusting the Width of the support, said adjustment involving axialmovement of a trunnion in a bearing.

In testimony whereof I have hereunto set my hand.
